Troubleshooting Electric Nash 22H
Hi Everyone, my name is Kevin and I'm new to the RV world; picked up a 2004 22H Nash trailer a few weeks ago. I'm unable to get anything to run off of the battery when I'm not plugged in to shore powe...

trailer has 2 electrical systems
A 120V AC for microwave, A/C Unit, outlets and electric heat elements in fridge/water heater plus feed to converter
12V DC for lights, water pump, furnace, t-stat controls (A/C & Furnace), control circuits for fridge/water heater, jacks/tongue etc.
Converter will supply 12V DC and recharge battery when you are hooked up to shore power (or using generator)
Battery supplies 12V DC system when not hooked up to AC power source
POS cable from battery....trace it
S/B an in-line fuse (or small 2 stud box---DC circuit breaker) on/under trailer tongue frame before POS cable goes inside trailer.
Also converter will have 1 or 2 larger amp fuses (30A or so) for 'reverse polarity' protection if battery cables get hooked up backwards.
